Abstract
A high power amplifier (10) includes intelligent independent fault tolerant amplifying modules (11). Each of the modules (11) includes a power amplifier (17) having a plurality of silicon carbide transistor circuits (27-30) coupled in parallel and driven by a silicon carbide transistor circuit (26). The module (11) also includes a dedicated hybrid controller (18) that monitors the operational conditions of the power amplifier (17) and optimizes these operational conditions in order to provide fault isolation and to avoid unwanted failure of the module (11) as a whole.
